SHULTZ BUTTRESSES PLEA ON SALVADOR
Secretary of State George P. Shultz said today that the United States had a moral obligation not to allow concerns over human rights violations in El Salvador to lead to abandonment of that nation to ''a brutal military takeover by a totalitarian minority.'' In a wide-ranging defense of the Administration's policy in Central America, Mr. Shultz said it was crucial that Congress restore the military aid it had cut for El Salvador and thus create a ''shield'' behind which free elections and economic development can occur. 'Depends on the Congress' ''Whether we will be able to help provide this shield in time depends on the Congress,'' Mr. Shultz said in a speech in Dallas to that city's World Affairs Council and Chamber of Commerce. ''In the middle of a war, the Congress has cut security assistance by twothirds below the previous fiscal year. Here you are in the army and you're fighting, and all of a sudden the flow you need is cut by twothirds and people ask, how come the army isn't doing so well.''
